Application filed December 1,1903- Serial No. 183,328. (No model.)

To all whom it may concern:

Be it known that 1, CHARLES HAYEs CAs- PAR, of Newark, in the county ofEssex and State of New Jersey, have invented a new and ImprovedVentilating System, of which the following is a full, clear, and exactdescription.

This invention refers to a ventilating system that is arranged toexhaust the air from rooms or the chambers of a building and transmit itto the open air in a cheap and positive manner. I

Another object is to provide a system in which the air is not expelleddirectly into the open air, but travels through an intermediate orauxiliary chamber, thereby forming between the ventilated rooms and theopen air a protective layer.

The invention refers more particularly to the ventilating ofrefrigerating plants or cold storage buildings and is shown in thepresent case as particularly applied to a brewery structure.

The invention is illustrated in the accompanying drawing, whichillustrates a building in cross-section and being provided with threesets of rooms a a, Z) I), and c 0.

Running down on either side inside the wallslO are vertical pipes 11,that have the inlets 12 suitably arranged, but illustrated in the lowerpart of the rooms, and a regulatinghandle 13 can be placed to regulatethe amountof air admitted to the pipes 11. These pipes 11 lead the airto the pipes 1a and 15 and through a pressure-regulator 16 and thenceinto an exhauster 17. This exhauster can be driven by any suitable powerand emptied by means of the pipe 18 into an air-space 19. This airspacelies between the ceilings 20 of the rooms a a and the floor 21 ot theauxiliary chamber 22. The outlets 23 of the air-space 19 allow the airthen to flow into the auxiliary chamber 22, and an outlet 24 in the rootadmits of the final outlet of the air. Now taking it for granted that abrewery is being ventilated, the chambers a a would probably be thefermenting-rooms, I) 6 would be the lager-cellars,

and c 0 would be the chip-cellars. As is usual in breweries, the air istaken from the bottom of the rooms, as shown in the drawings, and wouldpass up through the regulator and the exhaust and would be forced intothe airspace 19. Usually with the ordinary construction of ceiling oreven with a closed air space between the ceiling and the roof the lowtemperature in the fermenting-room or in the rooms nearest the roofacting on the ceilings and the lower temperature from the outsideatmosphere acting on the opposite side of the ceilings would cause asweating on the ceiling that is very objectionable where open tanks orvats are used, as in the termenting-rooms of breweries. One of theobjects of my invention is to overcome this sweating, and the cold airfrom the rooms being forced into this air-space and passing from thereout into the open spaee22 forms layers of air-spaces ofgradually-increasing temperature toward the open air. Of course it willbe understood that the space 22 can be a small housing over the roof, orit can be, as in the illustration, a space between the ceiling of theupper floor and the roof. Tl necessary, an outlet 25 can be arranged onthe outlet 18 with a suitable regulatingmeans, and the outlet can thusbe directed directly into the open space 22, as will be evident.

The pressure-regulator 16 can be of any suitable construction and isarranged to regulate the outlet of air from the chambers when theadjusting means 13 are opened or closed.

Ilrliaving thus fully described my invention, 1 claim as new and desireto secure by Letters Patent 1. A ventilating system, comprising abuilding, a set of rooms therein, pipes arranged to draw the air fromthe rooms, an air-space above the rooms, the pipes emptying into theairspace, an auxiliary chamber, ducts from the air-space to theauxiliary chamber, and an outlet from the auxiliary chamber to theatmosphere.

2. Aventilatingsystem, comprisingabuilch ing, a series of pipesarranged. to withdraw the air from the chambers of the building, adfromthe air-space into an auxiliary chamber gustable inlets arranged in theseries of piping and an outlet from the auxiliary chamber into adaptedto admit the air from the rooms into the the atmosphere.
